Is BMS Biomedical Sciences? Have you got any guidelines, exemplar reports, marking guidelines etc? If not, maybe you could look at scientific papers? The structure will be similar.
When you do experiments/lab sessions, is it a specific experiment or do you collect data and are expected to collect data and use that to come up with a hypothesis?
Eg Are you told you are doing an investigation into how the red blood cell parameters vary between males and females or would you go into class, take blood samples, do various tests, record other data, such as sex, age, ethnicity and be left to come up with a title, hypothesis etc yourself?
The structure would be something along the lines of:
A title (be accurate, if you were looking at differences in red blood cell parameters in males and females but all your data comes from healthy 20 somethings you might want to specify that).
An abstract/introduction/aims & hypothesis type section where you give a brief background to the subject area with references, what the aim of the experiment is, the type of study it is (there are different kinds of experimental design eg double blind trial), give a justified hypothesis etc
A method: equipment used, procedure, details of how you will analyse the data etc
Results: present the raw data in the best way to visualise what you are trying to show eg tables, graphs, pie charts etc Then describe trends, analyse the data statistically to see if it is significant. I'm guessing you have been taught how to choose the correct statistical tests to perform or you are told which ones to use if you haven't learnt that yet? There are plenty of online guides on which tests to use for different types of data.
Discussion & Conclusion: summarise the main findings. Then align the discussion to your aims/hypothesis, refer to other research that supports/contradicts your findings, discuss issues that might have affected your results eg if you were looking blood pressure, stress caused by taking the test could have caused anomalies in some subjects, then give a conclusion that is supported by your results eg in the example of red blood cell parameters, RBC is lower in females than males.
